The catalogue also references aluminium alloy 6063‑T5 frames combined with tempered safety glass, reflecting common construction specifications.

The listed items fall under the broader category of Cupboards, Doors, Gates, Grills & Windows, and also touch on Panels and Curtains as secondary categories. Products such as the "Spain Balcony Glazing System" and "Finland Balcony Glazing System" carry HS 7008.00 for insulated glass units, while the "Frameless Glass Folding Door" is classified under HS 7009.40 for glass doors. Materials specified include aluminium alloy 6063‑T5, thermal‑break aluminium, and tempered or laminated safety glass. The catalogue includes both fixed glazing solutions and movable systems like sliding, folding and stackable panels. Several entries lack HS codes, indicating they may be custom or ancillary components.

Product Range and Specialties of Shanghai Finzone Windows & Doors Co., Ltd

The catalogue offers a variety of aluminium‑frame window and door systems, most of which are built from aluminium alloy 6063‑T5 and feature tempered safety glass or double‑glazed units. Typical industry grades for this alloy meet EN 755‑2 extrusion tolerances and provide a tensile strength around 190 MPa, while thermal‑break profiles incorporate polyurethane inserts to lower thermal conductivity to about 0.025 W/m·K. Glass components are commonly supplied in thicknesses from 6 mm for single glazing to 24 mm for laminated safety glass, meeting EN 12150 or EN 14607 safety standards. Buyers also encounter frameless sliding doors, folding balcony systems and stackable wall panels that combine aluminium extrusion with glass panels, often finished with anodized or powder‑coated surfaces for corrosion resistance.

In the wider market, aluminium window systems are classified under HS 7610.10 for complete units with frames and glass, and HS 7610.90 for ancillary aluminium components. Glass‑only products fall under HS 7007‑7009, covering tempered, laminated and insulated glass units. Industry buyers typically require CE marking for EU shipments, ASTM standards for the US, and ISO 9001 quality management certification from manufacturers. Standard performance data such as U‑values (0.8‑1.2 W/m²K for double‑glazed units) and solar heat gain coefficient (SHGC 0.25‑0.45) are used to compare products.

Trade and Export Information - Shanghai Finzone Windows & Doors Co., Ltd

China is a leading exporter of aluminium window and door systems, supplying the European Union, North America, the Middle East and Southeast Asian construction markets. HS 7610.10 units are subject to anti‑dumping duties in some regions, and customs authorities often request a certificate of origin and conformity declarations such as CE or ASTM. Glass items under HS 7007‑7009 may require additional testing reports for safety glazing and, where applicable, energy‑efficiency certificates for insulated glass units. Export logistics commonly involve palletised loads in 20‑ft or 40‑ft containers, with protective film and edge protectors to prevent breakage; Incoterms such as CIF or FOB Shanghai are typical. Chinese manufacturers usually adhere to national standards GB/T 8478 for aluminium windows and GB 15763 for safety glass, which align closely with international EN and ASTM specifications.

Sourcing from Shanghai Finzone Windows & Doors Co., Ltd - Buyer Guidance

When sourcing from this supplier, buyers should request a full product data sheet that lists the aluminium alloy temper, glass thickness, thermal‑break specifications and any surface treatment. Material certificates confirming alloy composition (Al‑Si‑Mg) and temper (T5) together with glass safety test reports (EN 12150/EN 1363) are essential for compliance verification. Buyers are advised to ask for CE Declaration of Conformity or equivalent ASTM test reports if the target market requires them, as well as a sample unit to assess fit, finish and operation of sliding or folding mechanisms. Verification of the correct HS code on the commercial invoice, along with a certificate of origin, helps avoid customs delays. Typical minimum order quantities range from 500 to 1,000 units per model, and lead times are generally 30‑60 days after order confirmation, depending on the complexity of glazing and frame finishes.

Which HS codes are used for the aluminium sliding window products?

The aluminium sliding windows and doors are classified under HS 7610.10, which covers aluminium structures for building frames with glass. Some specialty units such as slide‑and‑turn windows fall under HS 7610.90 for other aluminium building components.

What material standards apply to the aluminium alloy used in the frames?

The frames are made from aluminium alloy 6063‑T5, a widely used temper for architectural extrusions that meets EN 755‑2 for extrusion tolerances and provides good corrosion resistance. Buyers often request a material certificate confirming the alloy composition and temper.

Which glass safety standards are relevant for the tempered glass listed?

Tempered safety glass typically complies with EN 12150 (tempered glass) and EN 1363 (safety glass). Laminated variants follow EN 14607. Buyers should ask for a test report confirming the glass meets the required safety classification and impact resistance.

What are typical packaging and shipping methods for these window and door units?

Products are usually palletised with protective wooden crates, wrapped in film, and loaded in 20‑ft or 40‑ft containers. The glass panels are separated with edge protectors and foam to prevent breakage during transit.

What documentation should a buyer request before placing an order?

Buyers should request a product data sheet, material certificates for aluminium alloy, glass safety test reports, CE or equivalent conformity declarations, and a sample of the finished unit if possible. Verifying the HS code and country of origin on the commercial invoice is also standard practice.

What are common minimum order quantities and lead times for these systems?

For standard aluminium sliding windows and balcony glazing systems, suppliers often set a MOQ of 500‑1,000 units per model, with lead times ranging from 30 to 60 days after order confirmation, depending on the complexity of the glazing and frame finishes.

Are thermal‑break frames available for the aluminium products?

Yes, several catalogue items specify a thermal‑break aluminium profile, which reduces thermal bridging and improves energy performance. Buyers usually request the thermal conductivity value (W/m·K) and U‑value calculations for the complete window assembly.

Which markets commonly import Chinese aluminium window systems?

Major import markets include the European Union, the United States, the Middle East and Southeast Asia, where builders seek CE‑marked or ASTM‑tested products for residential and commercial projects.
